Domark 230 ME is not listed at this time, but is labeled at a rate of 4 to 6 ounces per acre.

When deciding to spray a fungicide, consider these factors in decision making:

Southern corn rust.

• When will the corn reach maturity — early maturing corn may escape infection and you might want to concentrate on the late maturing hybrids.

• Strobilurins provide excellent control of rust in general, but their residual is fairly short and they have limited systemic movement in plants. Triazoles such as Domark, Proline (Proline is a component in Stratego Yld) are more systemic thus more forgiving of less than perfect application.

• Application costs may actually be greater than fungicide costs in many instances, so consider using the higher fungicide rate which will provide more residual protection and try to get by with one application.
